Brain Sleep refers to the period of approximately 90 minutes immediately after falling asleep, when the deepest non-REM sleep occurs, as the "Golden 90 Minutes." During these 90 minutes, five important physiological phenomena for sleep are particularly active: "brain and body rest," "memory organization and consolidation," "hormone balance adjustment," "immune system boost," and "removal of brain waste products." What is important in getting sleep is not just the "duration, but also the quality." For Japanese people, who tend not to get enough sleep, taking deep and slightly longer sleep during the first 90 minutes of sleep can lead to an improvement in sleep quality. The proportion of S3, the deepest stage of non-REM sleep, significantly increased during the Golden 90 Minutes compared to general functional pillows.

Made from unique materials and composed of over 90% air layers, it prevents heat and humidity from accumulating during sleep, creating a comfortable sleep environment. Designed with meticulous attention to both material and construction, based on sleep medicine Provides your optimal sleep environment, using 100% recyclable, sustainable materials. 3-layer x 7-gradation structure design The pillow has a rational structure, consisting of an "adjust layer" that conforms to the size and weight of your head, a "support layer" that firmly supports your head and neck, and a "base layer" that allows air to escape from below. These three layers vary in fiber thickness and density. The neck area is soft and easy to sink into, while both ends are slightly firmer, providing a good fit even when sleeping on your side and making it easy to turn over. Washable for hygiene It is said that humans sweat about one cup (approx. 200ml) while sleeping. Since over 90% of the pillow consists of air layers, it boasts excellent breathability, preventing moisture buildup and promoting hygiene. Furthermore, not only is the cover washable, but the inner material can also be rinsed with water and dries quickly, ensuring it stays clean at all times.
